2 Samuel 17:9; 2 Samuel 18:17

9 "Behold, he has now hidden himself in one of the caves or in another place; and it will be when he falls on them at the first attack, that whoever hears it will say, 'There has been a slaughter among the people who follow Absalom.'

17 They took Absalom and cast him into a deep pit in the forest and erected over him a very great heap of stones. And all Israel fled, each to his tent.
